' wres er nim cmne laia a seam-wee p -SON, a citizen of the United gStates residing at Aurora, in the .gzounty of; jjBrook ngs and State of South Dakota, have invented certai new and usefu Improvement in Bel Couplings; and T do declare the following i to be a full, clear, and exact descriptign of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in belt couplers and more particularly to the types employing a hinge connection.

One object of the invention is to provide a very simple and eflicient hinge or coupler which will securely lock the two ends of the belt together;

Another object is to provide means for preventing the ends of the pintle from coming in contact with objects such as belt shifters along its course of travel.

A further feature of the invention is in the construction of a hinge or coupler of the character described, whereby the united ends of the belt provide means for preventing the pintle from turning and thereby released during the travel of the belt.

With these objects in view, the invention resides in certain novel features of construction and combination of parts which will be clearly defined in this specification and in the claim appended hereto.

In the drawings: Figure 1 is a perspective view of my coupler and the joined ends of the belt connected thereby. Fig. 2 is a plan view thereof. Fig. 3 is an edge view partly in section. Fig. 4; is a transverse section taken on the line 4-4 of Fig. 2, and Figs. 5

and 6 are horizontal sectional views showing the manner in which the pintle must be removed.

By reference to the accompanying drawing, it will be seen that my invention comprises two companion hinge members 1 and 2, each of which is formed in a well known manner by bending a metal plate upon itself and cutt-in notches 3 therein forthe purpose of receiving the loops 4 on the ad- .5 h e nafite .iia rihesi- Thi pie le i i so a len app ox at y equal 420 he Wi of h h g m m rs ab v descr e and-i ada ifQr i eme e agemen with th loops 4, whereby a flexible separable connect m i r vided- A 11 reset l te fromphe end of the pih tle nd 'is, adapted th come into en agement with one'of the outer loops 4 and t us prevent the removal of said pintle provided it. be held from turning. The gist of the present invention resides in the specific means for preventing this pintle 5 from turning. This is accomplished by forming an elongated head 7 (of less width than the belt) on the end of the pintle opposite the lug 6 and so securing the ends of the belt 8 between the clamping plates 1' and 2' that the edges thereof project beyond the edges of said plates and the space be-' tween these joined ends will be slightly less than the length of the head 7. With this structure it will be clearly seen that when the head of the pintle is turned to bring it in linewith the belt, the ends of the head will embed themselves in the ends of the belt, thus forming an efficient lock for preventing the casual turning of the pintle and prob-. ably the loss of the same.

When it is desired to separate the coupler as for removing the belt in such a place that would not permit slipping it from'the pulley, my device is very convenient as all that is necessary is to turn the head of the pintle until the lug 6 is out of engagement with the outer loop 4 and said plntle is free to move laterally as shown in Fig. 5, until the next loop interferes. Then by giving pintle another half turn, the lug 6 will travel in the spaces between two of the loops 4 and the pintle will then be free to be pulled farther out of the loops as shown in Fig. 6. It will be seen that by repeating this movement, the pintle may be entirely removed and by reversing said movements, it may be inserted.

Particular stress is laid on the projecting of the belt beyond the edges of the coupler, thereby not only forming. an efficient lock for the pintle of the coupler, but forming a protection for the projecting ends thereof which is very important in cases where a forked belt shifter is employed.

From the foregoing description taken in co ne t n ith t e a compa ying drew the ing, the construction and operation of the device will be clearly understdod without uiring a more extended explanation.

at is claimed as new is:-

The combination with the meeting edges of a belt, of a coupler connected thereto and composed of two hinge sections each having parallelattaching plates, the latter being narrower than the width of the belt 4 whereby the edges of the belt are exposed beyond the plates, bin e loops connecting sald plates and lateralg spaced a greater distance than the widt of said 100 s, a pintle removablyengaged with said oops and having a laterally projecting lug on one end and an elongated head on its opposite end, the o posite endstof which head are adapted to turned into binding and elding engagement with the unprotect connected ends of the belt, whereby the pintle is prevented from turning and the head thereof protected by. the thicknm and ed as of the belt.

testimony whereof I have hereunto set my hand in presence of. two subscribing witnesses.
